Solution Overview

Problem

Existing component insertion assembly devices with chuck devices face interference issues during clamp release, leading to defects when mounting components with narrow gaps, which limits higher density mounting due to the need for gaps between components to prevent clamping claw interference.

Innovation Solution

A component insertion assembly device with a chuck device featuring a clamping section, a pusher section, and air cylinder sections, where the opening amount of the clamping section during clamp release is minimized to avoid interference, and the chuck device is moved perpendicular to the clamp release direction to avoid collisions with adjacent components, allowing for narrow gap mounting and higher density component placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the clamping claws are opened wider during clamp release movement, then the clamping claws can release the component, but the clamping claws interfere with adjacent already mounted components

Engineering Contradiction:
Improveclamp release movementVSAvoidinterference with adjacent components
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a new movement dimension by moving the chuck device in the horizontal direction (perpendicular to the clamp release direction) in addition to the vertical clamp release movement. This dimensional change allows the clamping claws to clear adjacent components during clamp release, enabling narrow gap mounting without interference.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If gaps are left between components, then clamping claw interference is avoided, but component mounting density cannot be increased

Engineering Contradiction:
Improveavoidance of clamping claw interferenceVSAvoidcomponent mounting density
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

By adding horizontal movement to the chuck device operation, the patent eliminates the need for large gaps between components. The chuck can move horizontally to clear adjacent components during clamp release, allowing components to be mounted with narrow gaps while maintaining reliability and increasing mounting density.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Object-affected harmful factors

If the chuck device is moved horizontally after clamp release, then interference with adjacent components is avoided, but the operation sequence becomes more complex

Engineering Contradiction:
Improveinterference during raisingVSAvoidmovement control sequence
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent performs the horizontal movement of the chuck device immediately after clamp release, before the raising operation. This preliminary action in the correct sequence ensures that the clamping claws are positioned to clear adjacent components before any potential interference can occur during raising, managing complexity through proper sequencing.

Inventive Principle:
Principle #10Preliminary action

AI summary

Set the opening amount of clamping claws 51 to the minimum amount, or an amount close to that, such that clamping claws 51 of chuck device 10 do not interfere with adjacent already mounted components during clamp release movement. Raise chuck device 10 after leads 52 of component 50 have been inserted into holes 54 of board 53 by the push movement of pusher section 55 after moving clamping claws 51 to a retract position at which interference with component 50 does not occur during raising by moving chuck device 10 in a direction away from component 50 in a direction perpendicular to the clamp release direction of clamping claws 51 after the clamp release movement of clamping claws 51 which is after the lower end of leads 52 of component 50 have been inserted into holes 54 of board 53 by clamping leads 52 of component 50 with clamping claws 51.
